400 Bad request

The request body or query was malformed or failed validation. `detail` says which field.

Retry only after changing the request

What causes it

• A missing required field, a wrong type, or an unparseable JSON body.

How to fix it

• Fix the request against the OpenAPI schema. Retrying the identical payload will fail identically.

Example response

HTTP/1.1 400
Content-Type: application/problem+json

{
  "type": "https://sealdeal.ai/errors/bad-request",
  "title": "Bad request",
  "status": 400,
  "detail": "..."
}

`type` is stable and safe to branch on in code. `detail` is specific to your request and is the field to read for the particulars; its wording may change.
